	The Company’s U.S. federal agency portfolio consists of securities issued by the government-sponsored agencies of Federal Home Loan Mortgage Corporation (“FHLMC”), Federal National Mortgage Association (“FNMA”) and Federal Home Loan Bank (“FHLB”). The receipt of principal and interest on U.S. federal agency obligations is guaranteed by the respective government-sponsored agency guarantor, such that the Company believes that its U.S. federal agency obligations do not expose the Company to credit-related losses. Based on these factors, along with the Company’s intent to not sell the securities and its belief that it was more likely than not that the Company will not be required to sell the securities before recovery of their cost basis, the Company believed that the U.S. federal agency obligations identified in the tables above were temporarily impaired.
	The Company’s portfolio of municipal obligations consists of both tax-exempt and taxable general obligations securities issued by various municipalities. As of March 31, 2015, the Company did not intend to sell and it is more likely than not that the Company will not be required to sell its municipal obligations in an unrealized loss position until the recovery of its cost. Due to the issuers’ continued satisfaction of the securities’ obligations in accordance with their contractual terms and the expectation that they will continue to do so, the evaluation of the fundamentals of the issuers’ financial condition and other objective evidence, the Company believed that the municipal obligations identified in the tables above were temporarily impaired.
	The Company’s agency mortgage-backed securities portfolio consists of securities underwritten to the standards of and guaranteed by the government-sponsored agencies of FHLMC, FNMA and the Government National Mortgage Association (“GNMA”). The receipt of principal, at par, and interest on agency mortgage-backed securities is guaranteed by the respective government-sponsored agency guarantor, such that the Company believed that its agency mortgage-backed securities did not expose the Company to credit-related losses. Based on these factors, along with the Company’s intent to not sell the securities and the Company’s belief that it was more likely than not that the Company will not be required to sell the securities before recovery of their cost basis, the Company believed that the agency mortgage-backed securities identified in the tables above were temporarily impaired.
	The table below includes scheduled principal payments and estimated prepayments, based on observable market inputs, for agency mortgage-backed securities. Actual maturities will differ from contractual maturities because borrowers have the right to prepay obligations with or without prepayment penalties.
	The amortized cost and fair value of investment securities at March 31, 2015 are as follows:
	(Dollars in thousands)		Amortized		Estimated
			cost		fair value

Securities with carrying values of $192.0 million and $212.9 million were pledged to secure public funds on deposit, repurchase agreements and as collateral for borrowings at March 31, 2015 and December 31, 2014, respectively. Except for U.S. federal agency obligations, no investment in a single issuer exceeded 10% of consolidated stockholders’ equity.

	Loans, net		$	417,147		$	416,190
	During the quarter ended March 31, 2015, the Company adjusted the historical loss analysis within the evaluation of the allowance for loan losses. The Company previously used a twelve quarter historical loss rate calculated by loan class. The updated historical loss analysis uses a migration analysis to track historical losses by loan class and risk categories over a longer period of time. The adjusted historical loss analysis more accurately allocates estimated losses. The adjustments resulted in reclassifications of the allocated allowance between various loan classes as of March 31, 2015 compared to December 31, 2014. The adjustments to the historical loss analysis did not have a significant impact on the total allowance for loan losses balance as of December 31, 2014. The following tables provide information on the Company’s allowance for loan losses by loan class and allowance methodology:

The Company recorded net loan recoveries of $1.6 million during the first quarter of 2015 compared to net loan charge-offs of $50,000 during the first quarter of 2014. The net loan recoveries during the first quarter of 2015 were primarily associated with the recovery of $1.7 million on a $4.3 million construction loan which was fully charged-off during 2010 and 2011. As of March 31, 2015, the Company has recovered approximately $2.4 million of the loan and continues to pursue collection of the remaining amount.
The Company’s impaired loans decreased from $10.7 million at December 31, 2014 to $10.5 million at March 31, 2015. The difference between the unpaid contractual principal and the impaired loan balance is a result of charge-offs recorded against impaired loans. The difference in the Company’s non-accrual loan balances and impaired loan balances at March 31, 2015 and December 31, 2014, was related to troubled debt restructurings (“TDR”) that are current and accruing interest, but still classified as impaired. Interest income recognized on a cash basis was immaterial during the three months ended March 31, 2015 and 2014. The following tables present information on impaired loans:

The Company’s key credit quality indicator is a loan’s performance status, defined as accruing or non-accruing. Performing loans are considered to have a lower risk of loss. Non-accrual loans are those which the Company believes have a higher risk of loss. The accrual of interest on non-performing loans is discontinued at the time the loan is ninety days delinquent, unless the credit is well secured and in process of collection. Loans are placed on non-accrual or are charged off at an earlier date if collection of principal or interest is considered doubtful. There were no loans ninety days delinquent and accruing interest at March 31, 2015 or December 31, 2014. The following tables present information on the Company’s past due and non-accrual loans by loan class:

Under the original terms of the Company’s non-accrual loans, interest earned on such loans for the three months ended March 31, 2015 and 2014, would have increased interest income by $120,000 and $203,000, respectively. No interest income related to non-accrual loans was included in interest income for the three months ended March 31, 2015, and 2014.
The Company also categorizes loans into risk categories based on relevant information about the ability of the borrowers to service their debt such as current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis is performed on a quarterly basis. Nonclassified loans generally include those loans that are expected to be repaid in accordance with contractual loan terms. Classified loans are those that are assigned a special mention, substandard or doubtful risk rating using the following definitions:
Special Mention: Loans are currently protected by the current net worth and paying capacity of the obligor or of the collateral pledged but potentially weak. These loans constitute an undue and unwarranted credit risk, but not to the point of justifying a classification of substandard. The credit risk may be relatively minor, yet constitutes an unwarranted risk in light of the circumstances surrounding a specific asset.
Substandard: Loans are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged. Loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Loans are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.
Doubtful: Loans classified doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable.
The following table provides information on the Company’s risk categories by loan class:

At March 31, 2015, the Company had ten loan relationships consisting of sixteen outstanding loans that were classified as TDRs. During the first three months of 2015, the Company classified a $44,000 agriculture loan relationship consisting of two loans as a TDR after extending the maturity of the loans. Since the loans were adequately secured, no charge-offs or impairments were recorded against the principal as of March 31, 2015. During the first quarter of 2015, a $78,000 commercial loan, which was classified as a TDR during 2014, paid off. No loan modifications were classified as TDRs during the three month period ended March 31, 2014.
The Company evaluates each TDR individually and returns the loan to accrual status when a payment history is established after the restructuring and future payments are reasonably assured. There were no loans modified as TDRs for which there was a payment default within 12 months of modification as of March 31, 2015 and 2014. At March 31, 2015, there were no commitments to lend additional funds on any loan classified as a TDR. The Company had no allowance recorded against loans classified as TDRs at March 31, 2015 or December 31, 2014.

Fair value at December 31, 2014 was determined using discount rates ranging from 9.50% to 9.52%, prepayment speeds ranging from 5.05% to 12.04%, depending on the stratification of the specific mortgage servicing right, and a weighted average default rate of 2.25%.
	The Company had a mortgage repurchase reserve of $427,000 at March 31, 2015 and December 31, 2014, which represents the Company’s best estimate of probable losses that the Company will incur related to the repurchase of one-to-four family residential real estate loans previously sold or to reimburse investors for credit losses incurred on loans previously sold where a breach of the contractual representations and warranties occurred. The Company did not incur any losses charged against the reserve or make any provisions to the reserve during the first three months of 2015. The Company charged $19,000 of losses against the mortgage repurchase reserve and recorded a $5,000 provision to the reserve during the first three months of 2014. As of March 31, 2015, the Company did not have any outstanding mortgage repurchase requests.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]		6	Fair Value of Financial Instruments and Fair Value Measurements
	Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:
	Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.
	Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
	Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.
	Fair value estimates of the Company’s financial instruments as of March 31, 2015 and December 31, 2014, including methods and assumptions utilized, are set forth below:

	Methods and Assumptions Utilized
	The carrying amount of cash and cash equivalents is considered to approximate fair value.
	The Company’s investment securities classified as available-for-sale include U.S. treasury securities, U.S. federal agency securities, municipal obligations, agency mortgage-backed securities, certificates of deposits and common stocks. Quoted exchange prices are available for the Company’s U.S treasury securities and common stock investments, which are classified as Level 1. U.S. federal agency securities and agency mortgage-backed obligations are priced utilizing industry-standard models that consider various assumptions, including time value, yield curves, volatility factors, prepayment speeds, default rates, loss severity, current market and contractual prices for the underlying financial instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace, can be derived from observable data, or are supported by observable levels at which transactions are executed in the marketplace. These measurements are classified as Level 2. Municipal securities are valued using a type of matrix, or grid, pricing in which securities are benchmarked against U.S. treasury rates based on credit rating. These model and matrix measurements are classified as Level 2 in the fair value hierarchy.
	It is not practical to determine the fair value of bank stocks due to restrictions placed on the transferability of FHLB and FRB stock.
	The estimated fair value of the Company’s loan portfolio is based on the segregation of loans by collateral type, interest terms, and maturities. The fair value is estimated based on discounting scheduled and estimated cash flows through maturity using an appropriate risk-adjusted yield curve to approximate current interest rates for each category. No adjustment was made to the interest rates for changes in credit risk of performing loans where there are no known credit concerns. Management segregates loans in appropriate risk categories. Management believes that the risk factor embedded in the interest rates along with the allowance for loan losses applicable to the performing loan portfolio results in a fair valuation of such loans. The fair values of impaired loans are generally based on market prices for similar assets determined through independent appraisals or discounted values of independent appraisals and brokers’ opinions of value. This method of estimating fair value does not incorporate the exit-price concept of fair value prescribed by ASC Topic 820 and is classified as Level 3.
	Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value, determined on an aggregate basis. The mortgage loan valuations are based on quoted secondary market prices for similar loans and are classified as Level 2.
	The carrying amount of accrued interest receivable and payable are considered to approximate fair value.
	The estimated fair value of deposits with no stated maturity, such as non-interest-bearing demand deposits, savings, money market accounts, and checking accounts, is equal to the amount payable on demand. The fair value of interest-bearing time deposits is based on the discounted value of contractual cash flows of such deposits. The discount rate is tied to the FHLB yield curve plus an appropriate servicing spread. Fair value measurements based on discounted cash flows are classified as Level 2. These fair values do not incorporate the value of core deposit intangibles which may be associated with the deposit base.
	The fair value of advances from the FHLB, subordinated debentures, and other borrowings is estimated using current yield curves for similar borrowings adjusted for the Company’s current credit spread and classified as Level 2.
	The Company’s derivative financial instruments consist of interest rate lock commitments and corresponding forward sales contracts on mortgage loans held for sale. The fair values of these derivatives are based on quoted prices for similar loans in the secondary market. The market prices are adjusted by a factor, based on the Company’s historical data and its judgment about future economic trends, which considers the likelihood that a commitment will ultimately result in a closed loan. These instruments are classified as Level 2. The amounts are included in other assets or other liabilities on the consolidated balance sheets and gains on sale of loans, net in the consolidated statements of earnings.
	Off-Balance-Sheet Financial Instruments
	The fair value of letters of credit and commitments to extend credit is based on the fees currently charged to enter into similar agreements. The aggregate of these fees is not material.
	Transfers
	The Company did not transfer any assets or liabilities among levels during the three months ended March 31, 2015 or during the year ended December 31, 2014.
	Valuation Methods for Instruments Measured at Fair Value on a Recurring Basis

Changes in the fair value of available-for-sale securities are included in other comprehensive income to the extent the changes are not considered other-than-temporary impairments. Other-than-temporary impairment tests are performed on a quarterly basis and any decline in the fair value of an individual security below its cost that is deemed to be other-than-temporary results in a write-down of that security’s cost basis.
Valuation Methods for Instruments Measured at Fair Value on a Nonrecurring Basis
The Company does not value its loan portfolio at fair value. Collateral-dependent impaired loans are generally carried at the lower of cost or fair value of the collateral, less estimated selling costs. Collateral values are determined based on appraisals performed by qualified licensed appraisers hired by the Company and then further adjusted if warranted based on relevant facts and circumstances. The appraisals may utilize a single valuation approach or a combination of approaches including the comparable sales and income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. Impaired loans are reviewed and evaluated at least quarterly for additional impairment and adjusted accordingly, based on the same factors identified above. The carrying value of the Company’s impaired loans was $10.5 million and $10.7 million, with an allocated allowance of $419,000 and $349,000, at March 31, 2015 and December 31, 2014, respectively.
Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value, determined on an aggregate basis. The mortgage loan valuations are based on quoted secondary market prices for similar loans and are classified as Level 2.
Real estate owned includes assets acquired through, or in lieu of, foreclosure and land previously acquired for expansion. Real estate owned is initially recorded at the fair value of the collateral less estimated selling costs. Subsequent valuations are updated periodically and are based upon independent appraisals, third party price opinions or internal pricing models. The appraisals may utilize a single valuation approach or a combination of approaches including the comparable sales and income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. Real estate owned is reviewed and evaluated at least annually for additional impairment and adjusted accordingly, based on the same factors identified above.

Regulatory Capital Requirements	3 Months Ended

Banking and Thrift [Abstract]
Regulatory Capital Requirements under Banking Regulations [Text Block]		7	Regulatory Capital Requirements
	Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Management believes as of March 31, 2015, the Company and Bank meet all capital adequacy requirements to which they were subject at that time.
	Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. On January 1, 2015, the Company and the Bank became subject to new capital rules (the “Basel III Rules”) that implemented the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision and certain changes required by the Dodd-Frank Wall Street Reform and Consumer Protection Act. The Basel III Rules are applicable to all U.S. banks that are subject to minimum capital requirements, as well as to bank and savings and loan holding companies other than “small bank holding companies” (generally, non-public bank holding companies with consolidated assets of less than $1.0 billion).
	The Basel III Rules have maintained the general structure of the current prompt corrective action framework, while incorporating increased requirements. The Basel III Rules include a new common equity Tier 1 capital to risk-weighted assets minimum ratio of 4.5%, raise the minimum ratio of Tier 1 capital to risk-weighted assets from 4.0% to 6.0%, require a minimum ratio of Total Capital to risk-weighted assets of 8.0%, and require a minimum Tier 1 leverage ratio of 4.0%. A new capital conservation buffer, comprised of common equity Tier 1 capital, is also established above the regulatory minimum capital requirements. This capital conservation buffer will be phased in beginning January 1, 2016 at 0.625% of risk-weighted assets and increase each subsequent year by an additional 0.625% until reaching its final level of 2.5% on January 1, 2019. The Bank made the one-time AOCI opt-out election on the first Call Report filed after January 1, 2015, which allows banks under $250 billion with a one-time opt-out election to remove the impact of certain unrealized capital gains and losses from the calculation of capital.
	As of March 31, 2015 and December 31, 2014, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action then in effect. There are no conditions or events since that notification that management believes have changed the institution’s category.
	The following is a comparison of the Company’s regulatory capital to minimum capital requirements at March 31, 2015 and December 31, 2014:

New Accounting Pronouncements and Changes in Accounting Principles [Text Block]		8	Impact of Recent Accounting Pronouncements
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The main provisions of the update require the identification of performance obligations within a contract and require the recognition of revenue based on a stand-alone allocation of contract revenue to each performance obligation. Performance obligations may be satisfied and revenue recognized over a period of time if: 1) the customer simultaneously receives and consumes the benefits provided by the entity’s performance as the entity performs, or 2) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or 3) the entity’s performance does not create an asset with an alternative use to the entity, and the entity has an enforceable right to payment for performance completed to date. Initially the amendments of the update were to be effective for public entities beginning with interim and annual reporting periods beginning after December 15, 2016, however the FASB recently voted to defer the implementation for one year, although that change has not yet been finalized. Management is evaluating the impact of adopting ASU 2014-09.
